/Template:Countdown

The template shows a countdown before an event and if started until the end of the event. All times are relative to UTC. It is advisable to add a time zone name for local dates.

Using this template, if you are before the "start" you will see:

Event starts: 2 Days, 2 Hours, 2 Minutes, 2 Seconds.

or if you are past the start but before the end:

Event ends: 2 Days, 2 Hours, 2 Minutes, 2 Seconds.

or if you are past the end:

Event has ended.
